CCTV News: The 9th Asian Winter Games are about to open, and all venues carrying all events are ready, and some venues have ushered in fierce competition in advance. It is understood that all the venues of this year's Asian Winter Conference were transformed using the original buildings, and the renovation is based on the principle of "energy-saving, environmentally friendly, green and low-carbon". Upgrading and renovation The old venues are renewed

The ice and snow projects of this Asian Winter Games are all upgraded by the renovation and upgrading of existing venues and facilities, and some venues have not undertaken the Asian Winter Games for the first time. For example, the speed skating hall has a history of 30 years. At the third Asian Winter Games in 1996, the speed skating competition was held here. After the newly renovated venue, 14 gold medals will be awarded at this Asian Winter Conference, which is also the venue with the largest number of gold medals. Energy-saving, environmentally friendly, green and low-carbon, simple but not simple

"Liji" is a highlight of this Asian Winter Conference venue. The renovation and upgrading takes "energy-saving, environmentally friendly, green and low-carbon" as the core principle, simple but not simple. New technologies, new materials and new designs have been invested heavily in all aspects such as insulation, lighting, and refrigeration. For example, the glass lighting belt with the original roof of the Speed ​​Skating Hall is more than 100 meters long and more than 20 meters wide after years of use, and the insulation effect is much worse than before. The organizer converted the roof into a new aluminum, magnesium, manganese material with insulation, and the area of ​​the glass lighting belt was reduced to more than 400 square meters, which not only ensures a certain amount of natural lighting, but also better achieves thermal insulation and energy-saving effects.
